This paper is a report of a study that examines the relationship between teacher participation in a multi-year, K-6 professional development effort and the "high stakes" science test scores of different student groups in 33 rural mid-west school districts in the USA. The professional development program involved 1,269 elementary school teachers…

In this study, we looked at the impact of our specially designed inquiry-based science courses for pre-service elementary teachers on their science content knowledge as measured by a high-stakes state certification test for elementary education. We conducted a pre/post-analysis of the certification test scores of 1,003 pre-service teachers. Cohort…

We used four different methods to determine the best means of assessing over 200 preservice elementary teachers' growth in knowledge of models and their use in K-8 classrooms while participating in the Science Capstone course that focused on the unifying themes of models in science. Each assessment method probed a different aspect of models (from…

The goal of this study was to examine the two related links of "research to teaching practice" and "teaching practice to research" that pre-service elementary teachers made during an action research project focusing on a conceptual-change teaching experience with elementary school students. Data were collected from the final written reports from…
